Abstract:
A practical and inexpensive method to measure the dose of dialysis without any laboratory tests is described. A prospective study was performed that suggested that the volume of blood treated during hemodialysis, corrected for postdialysis body weight (CBVpost), can be used as a simple method to measure dose of dialysis. In this study the dose of dialysis, measured as Kt/Vurea, and the volume of blood dialyzed, were compared for 195 hemodialysis treatments. There was a strong positive correlation between Kt/Vurea and CBVpost in the entire group of patients (r = 0.78). However, this correlation was strongest for traditional dialysis using dialyzers with a urea clearance of 170-180 ml/min (r = 0.82) than for other dialyzers.
